摘要: 基于笔划的油画生成是油画生成中最为重要的技术,它模拟真实画家使用
笔划的创作过程,以达到逼真的手绘作品的效果。分析了基于图像分割的区域笔划生成油画
的优缺点,提出一种融合区域笔划和梯度笔划的油画生成方法,首先通过图像分割生成区域
笔划,然后根据图像分割水平确定梯度阈值筛选出梯度笔划。通过实验可以看出,该方法生
成速度较快,不仅使笔划更加灵活多变,而且可以弥补区域笔划生成所产生的缝隙。

Abstract: Oil paintings rendering based on brushstrokes is the most import technology in oil
paintings rendering which simulates real artists’ painting process that use brushes to paint. This
paper analyzes advantages and disadvantages of oil paintings rendering based on region
brushstrokes through image segmentation, and presents a new method of oil paintings rendering
based on combining region brushstrokes with gradient brushstrokes. Firstly, render region
brushstrokes through image segmentation and then set gradient threshold through image
segmentation level and render gradient brushstrokes. Experimental results confirm that the method
has a rapid rendering speed, and not only makes brushstrokes more flexible but can fill up some
gaps rendered due to region brushstrokes.
